Towards a measurement of the $^{44}$Ti($\alpha $,p)$^{47}$V reaction
ORAL
Abstract
The detection of gamma-rays from the decay of the long lived radioisotope $^{44}$Ti (t$_{\mathrm{1/2}}=$ 60.0y) by satellite based observatories, has been associated with core collapse supernovae remnants. The detected amount of $^{44}$Ti in the interstellar medium might provide critical insight for understanding the explosion mechanism of core collapse supernovae. The rate of the $^{44}$Ti($\alpha $,p)$^{47}$V reaction is a key reaction which determines the final abundance of Ti produced in such explosive environment. We have successfully developed a $^{44}$Ti beam via the $^{42}$Ca(He,n) $^{44}$Ti reaction at the new in-flight Radioactive Ion Separator (RAISOR) at Argonne National Laboratory. Preliminary results on the development and characterization of a $^{44}$Ti beam will be presented as well as preparations on the use of this beam with the Multi-Sampling Ionization Chamber (MUSIC) detector to measure the $^{44}$Ti($\alpha $,p)$^{47}$V reaction in the astrophysically relevant energy region.
