Description

To investigate 5H resonance states it is utilized the two-neutron transfer reaction 3H(t, p)5H a cryogenic liquid-tritium target and 57.5-MeV triton beam. A valuable fraction of protons detected at θlab = 18 deg-32 deg in ptn coincidence events was attributed to the states of 5H. Two resonance states situated at 1.8 ± 0.1 and 2.7 ± 0.1 MeV above the t + n + n decay threshold were obtained in the energy spectrum of 5H. A state of 4H was obtained in the reaction 2H(t, p)4H from the spectra of protons detected in coincidence with neutrons emitted in the decay of 4H nuclei

Abstract (Russian)

Для исследования резонансных состояний (РС) используется реакция переноса 3H(t, p)5H на мишени из жидкого трития и 57.5 МэВ-тритонов. Значительная доля протонов, зарегистрированных при θлаб = 18 град-32 град при совпадении с ptn-событиями, приписана РС ядер 5Н. Два РС, расположенные на 1.8 ± 0.1 и 2.7 ± 0.1 МэВ выше порога распада t + n + n, были обнаружены в энергетическом спектре 5Н. Резонансное состояние ядра 4Н было получено в реакции 2H(t, p)4H из спектра протонов, зарегистрированных при совпадении с нейтронами из распада 4Н
