Estimation of radiative capture 13B(n, γ 0+1)14B reaction rate in the modified potential cluster model*

“…Shallow potentials are appropriate for the description of scattering states without resonances and should give phase shifts close to zero [22,23]. Deep non-resonance potentials should also provide the moderate energy dependence of phase shifts, which may be normalized according to the Levinson theorem (see details in [28]). In the case of resonance scattering states, the potential (6) should fit additional conditionsthe reproduction of the resonance position E c.m.…”

“…2 with FS from Table 1. Their phase shifts are normalized to 180(1)° according to the generalized Levinson theorem [28] (green dashed curve in Fig. 3).…”
