Z-dependence of the intensity of |Δn|=2 pionic X-rays

The intensity per stopped π^?of|Δn|=2 pionic X-rays are observed to have larger variations with atomic number Z than do the |Δn|=1. The 6–4 intensity has a well-defined maximum at Z=34 with a FWHM of ΔZ ～10.     

The reduction of nitroso-spin traps in chemical and biological sysetms. A cautionary note

The NaBH₄ or enzymatic reduction of 2-methyl-2-nitrosopropane results in a four-line ESR spectrum due to $\text{t}$-butyl hydroniroxide. This spectrum is identical to a previously reported ESR spectrum (C.S. Lai and L.H. Piette, Tet. Letters, $\text{9}$, 775 (1979)) obtained during a Fenton reactions using 2-methyl-2-nitrosopropane, which had been assigned to the hydroxyl radical adduct. This note presents evidence that this four line spectrum can arise from the chemical reduction of the spin trap.     

Rapidity density distributions in antiproton-proton collisions

Data on the density of charged particles in rapidity space for annihilation and non-annihilation p?p interactions at 7.3 and 12 GeV/c are reported. It is shown that the central rapidity density for non-annihilation processes is a simple linear function of $\text{ln}\text{(}\text{s}\text{)}$ from these low energies up to p?p collider energies ($\text{s}\text{=540}\text{GeV}$). Significant differences in density distributions for p?p and e^?e⁺ annihilations at comparable energies are found.     

The echocardiophone: A new means for observing spatial movement of the heart

The paper describes a new pocket size instrument called the ‘Cardiophone’ for the diagnosis of cardiac dysfunction. It is a continuous wave swept frequency ultrasonic echo-location system which produces dynamic auditory signals corresponding to the positional change of internal structures of the heart. The four valves are relatively easy to locate compared with conventional ECG machines. Preliminary clinical evaluation results are presented indicating the potential of the instrument for the general practitioner.

Inelastic scattering of He atoms from a Cu(110) surface

A He beam has been used to measure inelastic scattering from a Cu(110) surface. The scattering was a result of predominantly single phonon events and both energy gain and loss processes were observed. This was in contrast to Cu(001) where only energy loss was observed. For Cu(110), aligned in the [001] azimuth, partial dispersion relations have been measured which meant that phonons with ΔQ values up to the zone boundary value have not been detected under the present experimental conditions. The elastic incoherent component varied with azimuthal angle for Cu(110).
