Measuring the cross section of the $^{15}$ N( $α$ , $γ$ ) $^{19}$ F reaction using a single-fluid bubble chamber

D. Neto, K. Bailey, J. F. Benesch +17

$^{15}$ N( $α$ , $γ$ ) $^{19}$ F is believed to be the primary means of stellar nucleosynthesis of fluorine. Here we present the use of a single-fluid bubble chamber to measure the cross…

First direct measurement of the $^{13}$ N( $α$ , $p$ ) $^{16}$ O reaction relevant for core-collapse supernovae nucleosynthesis

H. Jayatissa, M. L. Avila, K. E. Rehm +10

Understanding the explosion mechanism of a core-collapse supernova (CCSN) is important to accurately model CCSN scenarios for different progenitor stars using model-observation com…

Cross sections of $α$ -induced reactions slightly below doubly-magic $^{40}$ Ca from the statistical model

P. Mohr, R. Talwar, M. L. Avila

New experimental data for the $^{38}$ Ar( $α$ ,n) $^{41}$ Ca and $^{38}$ Ar( $α$ ,p) $^{41}$ K reactions were used to find a best-fit set of parameters for statistical model calculations. Th…

Stellar $^{36, 38}$ Ar $(n, γ)^{37, 39}$ Ar reactions and their effect on light neutron-rich nuclide synthesis

M. Tessler, M. Paul, S. Halfon +22

The $^{36}$ Ar $(n, γ)^{37}$ Ar ( $t_{1/2}$ = 35 d) and $^{38}$ Ar $(n, γ)^{39}$ Ar (269 y) reactions were studied for the first time with a quasi-Maxwellian ( $k T \sim 47$ keV) neutron flux…

Probing the single-particle character of rotational states in $^{19}$ F using a short-lived isomeric beam

D. Santiago-Gonzalez, K. Auranen, M. L. Avila +19

A beam containing a substantial component of both the $J^{π} = 5^{+}$ , $T_{1/2} = 162$ ns isomeric state of $^{18}$ F and its $1^{+}$ , 109.77-min ground state has been utilized to study membe…

High- $j$ neutron excitations outside $^{136}$ Xe

R. Talwar, B. P. Kay, A. J. Mitchell +8

The $ν 0 h_{9/2}$ and $ν 0 i_{13/2}$ strength at $^{137}$ Xe, a single neutron outside the $N = 82$ shell closure, has been determined using the $^{136}$ Xe( $α$ , $^{3}$ He) $^{137}$ Xe react…
