On 12C +   Scattering by the Coupled Channel Resonating Group Method: Solution of the Redundancy and Non-Orthogonality Problem

The robust (spin and isospin zero) α-particle remains one of the best projectiles to probe the nuclear isoscalar excitations. In the present work, a microscopic folding model analysis of the α+12 C inelastic scattering to the 2+ (4.44 MeV), 0+ (7.65 MeV), 3- (9.64 MeV), 0+ (10.3 MeV) and 1- (10.84 MeV) states in 12 C has been performed using the 3-α resonating group method wave functions. The isoscalar transition strengths of these states were carefully studied based on the coupled-channel analysis using the microscopic folded form factors. A correlation between the weak binding and/or short lifetime of the excited state and absorption in the exit channel of inelastic scattering has been established.

Color Channels

A transformation table between physical bases including hidden color channels and symmetry bases for nonstrange six-quark systems is provided by using fractional parentage expansion method. By solving a coupled-channel equation, in the framework of the resonating group method (RGM), the effect of hidden color channels to all nonstrange six-quark systems is examined. It is shown that the overall effects from hidden color channels would reduce the energies of systems. For ΔΔ systems, the greatest decrease is about 20 MeV. Effects of hidden color on the masses of NN systems have been found to be about 1 MeV. However, we should emphasize that such a minor change for NN system is not negligible. We also give the most favorable hidden color channels for NN system.

We study 17 O and 18 O nuclei by using the core +n(+n) model. We perform the coupled-channel and the resonating group method (RGM) calculations not only for bound states but also for resonant states of 17 O . We obtain the state dependent core-n folding potential and reasonable single-particle energy (SPE) in the 16 O core. By using the same interaction for 17 O , we study 18 O in the core +n+n system.

Abstract. Background: Suicide is a pervasive and complex issue that can challenge counselors through the course of their careers. Research and practice focus heavily on crisis management and imminent risk rather than early intervention strategies. Early intervention strategies can assist counselors working with clients who have suicidal ideation, but are not at imminent risk, or with clients whose risk factors identify them as having a stronger trajectory for suicidal ideation. Aims: This systematic literature review examines the current literature on working with clients with suicidal ideation who are not at imminent risk, to ascertain the types of information and strategies available to counselors working with this client group. Method: An initial 622 articles were identified for analysis and from these 24 were included in the final review, which was synthesized using a narrative approach. Results: Results indicate that research into early intervention strategies is extremely limited. Conclusion: It was possible to describe emergent themes and practice guidelines to assist counselors working with clients with suicidal ideation but not at imminent risk.
