Angular Distributions of Protons fromNa23(d, p)Na24andTi47,48(d, p)Ti48,49

Sodium and titanium targets were bombarded with 10-Mev deuterons, and angular distributions of protons from the stripping reaction were observed with arrays of nuclear emulsions. Absorbing foils in front of each emulsion were arranged so that the integrated flux of protons in a limited energy range could be determined. Distributions were found for each of the four most energetic proton groups from sodium, corresponding to $Q$ values of 4.731 (ground state), 4.259, 4.167, and 3.390 Mev. The data were compared with the Butler theory, and $l_n$ values of 2, 2, 0, and 0, respectively, were necessary to fit theory to data. With ${\mathrm{Ti}}^{47}$ targets, $l_n$ values of 3, 1 (and 3?), 1, and 1, respectively, were determined for proton groups corresponding to $Q$ values of 8.14, 6.81, 5.83, and 4.83 Mev. With ${\mathrm{Ti}}^{48}$ targets, $l_n$ values of 3, 1, 1, and either 1 or 2 were determined for proton groups corresponding to $Q$ values of 5.81 (ground state), 4.46, 4.11, and 3.40 Mev, respectively. From these data, parity and possible spin values for the various states of ${\mathrm{Na}}^{24}$, ${\mathrm{Ti}}^{48}$, and ${\mathrm{Ti}}^{49}$ are deduced.
