Bularning barchasi neytron tezligining vertikal komponentini gorizontal nur tezligidan mustaqil ravishda davolash mumkinligini nazarda tutadi. Shunday qilib, agar eksperimentchilar tezlik komponentlarini bog'lashi mumkin bo'lgan har qanday mexanik yoki magnit ta'sirlarni bartaraf etish uchun etarlicha g'amxo'rlik qilgan bo'lsa, neytronlarning bo'shliq orqali o'tishi uning balandligi funktsiyasi sifatida erning kengligida chegarani ko'rsatishi kutiladi. -holat to‘lqin funksiyasi, undan keyin qo‘zg‘aluvchan holat to‘lqin funksiyalarining kengliklariga mos balandlikdagi qadamlar ketma-ketligi.
3 -rasmdagi qizil egri chiziq detektorga yetib boradigan neytron oqimining batafsil bashoratidir. Eshik chegarasi bo'lmagan ko'k egri chiziq - bu geometrik va fazoviy mulohazalardan hech qanday kvant effektisiz kutish mumkin bo'lgan narsa. Ma'lumotlar aniq kvant-mexanik bashoratni qo'llab-quvvatlaydi, ammo juda cheklangan statistika faqat birinchisidan keyingi kvant bosqichlariga ishora qilishi mumkin. Nesvijevskiy bizga shunday dedi: "Bizning tajribamiz milliard reaktor neytronidan faqat bittasini tanlas hi kerak edi".
Figure 3. Transmitted neutron flux as a function of gap height in the Laue–Langevin experiment shows a clear threshold near 15 µm and indications of steps at larger gap heights, consistent with the quantum-mechanical prediction (red curve). The blue curve is what one expects simply from the increasing phase-space acceptance of the gap. The horizontal line indicates the detector’s background level.
The experiment’s energy resolution is not limited only by statistics. The quantum-mechanical uncertainty relation
ΔEΔt≳ℏ����≳ℏ
also comes into play. The 0.01 s it takes a neutron to traverse the 10-cm-long gap in this experiment limits the energy resolution of the quantum-well eigenstates to 0.07 peV. One could, of course, do a hundred thousand times better if one could keep the neutron trapped in the well for its full lifetime—about 15 minutes.
